How to get thread number with parallel execution for Allure report timeline?

What are you trying to achieve?

I’m running tests in parallel with 4 chunks and write reports to Allure. I want to see tests from each chunk displayed in a separate timeline. If I manually add a “thread” label to each suite or test (in the XML) I can split the test results into multiple timelines.

What do you get instead?

By default in the Allure report all tests are displayed in one timeline.

I can add labels to test cases like

const allure = codeceptjs.container.plugins('allure');

Before(() => 
  allure.addLabel('thread', '...')
)

My question is - how can I get the chunk number in the test?

Details

• CodeceptJS version: 2.3.0
• NodeJS Version: 10.16.3
• Operating System: Windows 10
• Configuration file:

exports.config = {
  ...
  mocha: {
    reporterOptions: {
      reportDir: "./test/report",
      autoOpen: true,
    }
  },
  plugins: {
    allure: {
      enabled: true,
      outputDir: "./test/.output/allure-results"
    },
    stepByStepReport: {}
  },
  multiple: {
    parallel: {
      chunks: "4"
    }
  },
  bootstrap: false,
  teardown: null,
  hooks: [],
  tests: "./test/tests/ui/dashboard/*.js",
  timeout: 120000,
};

Running tests with

npx codeceptjs run-multiple parallel

@Naimadnap I’ve created an allureHelper

'use strict';

let Helper = codecept_helper;

class AllureHelper extends Helper {
    _before() {        
        let child = codeceptjs.config.get().mocha.child;
        // if there are child processes set thread label in Allure report to chunk number
        // child process name is like '1.parallel:chunk1:default'
        if(child) {
            const allure = codeceptjs.container.plugins('allure');
            allure.addLabel('thread', child.substring(0, child.indexOf('.')));
        }
    }
}

module.exports = AllureHelper;

and included it in codecept.conf.js

helpers: {
    Nightmare: {
      url: process.env.CODECEPT_URL || "http://localhost:3000",
      windowSize: "1920x1080",
      typeInterval: "-1"
    },
    allureHelper: {
      require: "./test/helpers/allureHelper.js",
    }
  },

@xMutaGenx thanks! Your solution is even better since it gives the actual chunk number.
